Maybe. But Google has been there in a sensor laden car, overhead with an airplane, and buying all the access that is available in satellite imagery, and fusing that together in a continually updated model. Plus real time data from a billion maps and navigation users. I pity the fool going up against that.
I don't think Waymo is using Street View / satellite data to drive. They have to build an HD map using a special LIDAR-equipped vehicle before deploying in a new area.
Maybe their navigation system will be better than the competition due to real-time traffic data from Google Maps users, but I don't think it'll be so much better as to be an unbeatable advantage.
